I built FireLookup because I kept seeing finance and operations teams waste hours reconciling Excel and CSV files with VLOOKUPs, helper columns, macros, and messy manual checks. The problem is simple but painful: two files rarely line up perfectly. References are slightly different, amounts are split across rows, dates don’t match cleanly, and reviewers still need a clear audit trail at the end. FireLookup is my attempt to make this workflow faster and cleaner. You upload two Excel or CSV files, choose the columns to match, run exact or fuzzy matching, and then review matched and unmatched rows before exporting the results. It is built for use cases like: - bank statement vs ledger reconciliation - invoices vs payments - orders vs settlement reports - exported reports from two different systems The goal is not to replace Excel completely. It is to remove the repetitive matching work that makes reconciliation slow, fragile, and hard to review. Every new account gets 1,000 free row credits, so you can test it with a real file. I’d love feedback from accountants, bookkeepers, FP&A teams, finance analysts, and anyone who still lives inside messy spreadsheets.
